Chlorine exposure appears to be cause of death of animals at UC Davis research center

A catastrophic failure" at a university research facility in California killed 21,000 fish this week, some of which were endangered.

The University of California, Davis, reported the loss of about 21,000 fish at its Center for Aquatic Biology and Aquaculture. Chlorine exposure, which the university noted fish are particularly sensitive to, appears to have caused the deaths.
